Title:
ELECTRONIC DEVICE, WIRELESS CHARGING RECEIVING APPARATUS, WIRELESS CHARGING CONTROL METHOD AND WIRELESS CHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/135751
Kind Code:
A1
Abstract:
Provided are an electronic device, a wireless charging receiving apparatus, a wireless charging control method and a wireless charging system, wherein same relate to the technical field of wireless charging, and are used for switching between a high-power fast charging mode and a low-power slow charging mode. A first communication circuit in a wireless charging receiving apparatus of the electronic device receives charging data, wherein the charging data is used for indicating a charging type. A first controller identifies that the charging type is a first charging type according to the charging data, outputs a first rectification control signal and controls a first rectification circuit to operate in a half-bridge mode. The first controller also identifies that the charging type is a second charging type according to the charging data, outputs a second rectification control signal and controls the first rectification circuit to operate in a full-bridge mode. A first receiving coil receives an alternating magnetic field and outputs a first induced voltage. The first rectification circuit converts the first induced voltage output by the first receiving coil into a direct-current power supply voltage, wherein the power supply voltage is used for supplying power to a battery.
